A testdrive with W3C’s Unicorn

It’s been about two weeks since the World Wide Web Consortium released Unicorn, it’s new all-in-one validator. The new service combines W3C’s markup validator, CSS validator, mobileOk checker, and feed validator. I’ve been using those services for a long time and use them on a daily basis. I’ve even incorporated the markup validator and the CSS validator in my semi-automated SEO scan.

A big improvement is that Unicorn is fast, and when I say fast, I mean really fast. The combined validation takes about as long as a validation with one of the individual services would take.

The biggest improvement however is having a single page for all your validation needs so you can see if something is wrong in one glance.
